Description
Size: Length of lorica 128-154 µm; maximum width of lorica 98-112 µm.

Lorica firm, sub rectangular, somewhat compressed dorso-ventrally, with a pattern of reticulate areolation as well as a simple pattern of ridges on the dorsal plate, both antero-dorsal and antero-ventral margins with spines, ten in number. Occipital medians longest and curve overhead ventrally. Pectoral medians shortest, straight. Intermediates on both margins and laterals about equal in length. Median notch between pectoral medians broader than notch separating occipital median spines. Posteriorly, lorica terminates in two spines, foot opening bounded by two short spines, equal in length to postero-laterals or somewhat shorter. Foot opening present in ventral plate, asymmetric in shape and position. Posterior portion of lorica asymmetrical.
